SICK Sensor Intelligence has unveiled its new DMM4 muting module, highlighting its commitment to industrial safety and access guarding.

The company claims that the DMM4 meets a wide range of muting needs and is reliable, flexible and configurable to deliver enhanced industrial safety without compromising productivity, the company notes.

SICK’s solutions

SICK provides safe access protection and light curtain muting and the DMM4 extension module represents the latest evolution in its complete portfolio of solutions.

The extension makes sure operators stay protected from hazardous machinery while materials, boxes and finished products move through smoothly.

The DMM4 is compatible with SICK’s deTec safety light curtains and deTem safety light-beam sensors for protection and efficiency with easy installation, the company notes.

DMM4

SICK’s DMM4 muting module is designed to perform in the field and can be easily integrated with all SICK deTec safety light curtains and deTem safety light-beam sensors to minimise the possibility of manipulation, while keeping workflows uninterrupted.

It doesn’t require a separate cabinet as its equipped with protection against dust and water in the field, reducing wiring and commissioning time.

The DMM4 is an innovation in entry/exit access guarding, equipped with a host of new tools, features and benefits to minimise false stops.

A dedicated muting module with a high IP rating, it can be used in safety function up to PLe (ISO 13849)/SIL3 (IEC 62061) and fully supports compliance with ISO 13855, the standard covering the requirements of positioning safeguards with respect to the approach of the human body.

The DMM4 is a more powerful, slimmer extension module than previous versions and SICK has released new support columns with micro adjustment capabilities and a built-in spirit level.

Expertise in safety light curtains

SICK has supplied safety light curtains since inventing the technology in 1946 and has a wealth of knowledge in the field.

The DMM4 provides more features than basic muting options and better flexibility at a lower cost than muting using a safety PLC or safety controller.

The free and intuitive SICK Safety Designer software enables easy and flexible configuration of muting parameters, smart functions and operating mode with key features including:

• Mode switch to store different configurations
• Smart restart interlock
• Access to a full diagnostics and error history

Applications for the DMM4 muting module range from logistics to manufacturing.

Suitability

The DMM4 muting module meets industry standards for safe material flow through electro-sensitive protective equipment (ESPE), accurately and reliably differentiating between material and a person to provide safe conditions, the company claims.

The most common configurations of photoelectric muting sensors are T and L layouts with two or four beams either in parallel or arranged as cross beams and control by way of timing or sequence.

“Out of the box certified”

Martin Kidman, Manager Safety (S&W Europe), SICK commented: “Highly flexible and configurable, the SICK DMM4 is out of the box certified and Plug and Play with easy installation and connectivity with the SICK deTec safety light curtain.

“It’s part of a complete range of SICK safety light curtain products, including light curtains, sensors, fittings and muting modules.”

Kidman concluded: “Speak to SICK’s application engineers to find out more about what our safety light curtains and the DMM4 muting module can bring to your business.”
